Installing an Interface Expansion Board
Insert connector
Secure holding screws
To make the connection, plug the cable connector into the serial interface port at the back right of the printer. Secure the connector by tightening the screws in the connector hood. Plug the other connector into your computer’s serial port. Consult your computer documentation if you need help.
Selecting the Serial Interface
The printer’s standard interface is parallel. When the serial interface board is installed, the printer automatically detects that the computer is using the serial interface.
Verifying Serial Parameter Settings
Next, you must make sure the serial parameter settings are the same between the computer and the printer. The reference manual explains the parameters. Consult your computer and software documentation to determine the settings your computer uses. Then compare these to the printer’s settings in the following table.
